78914630 ÷ 867 
Our goal is to divide 78914630 by 867.

Moving on to step 1:
When dividing 7 by 867, we get 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Append the next digit (8) from the dividend to 7 and continue with: 78 / 867

Going ahead to step 2:
78 divided by 867 is 0 with a remainder of 78.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 78 leaves us with 78.
Include the next digit (9) from the dividend after 78, then repeat: 789 / 867

Going ahead to step 3:
The number 867 fits into 789 0 times, leaving a remainder of 789.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 789, we get 789.
Take the next digit (1) from the dividend and append it to 789, then repeat: 7891 / 867

On to step 4:
The number 867 fits into 7891 9 times, leaving a remainder of 88.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
Subtract 7803 from 7891 to get 88.
Append the next digit (4) from the dividend to 88 and continue with: 884 / 867

Moving on to step 5:
884 divided by 867 is 1 with a remainder of 17.
The number 1 becomes the next digit in our result. 
Result so far: 91.0
Subtracting 867 from 884 leaves us with 17.
Fetch the next digit (6) from the dividend, attach it to 17 and continue: 176 / 867

Moving on to step 6:
When dividing 176 by 867, we get 0 with a remainder of 176.
Put 0 as the next digit of the answer. 
Result so far: 910.0
If we subtract 0 from 176, we get 176.
Append the next digit (3) from the dividend to 176 and continue with: 1763 / 867

Step 7:
1763 divided by 867 is 2 with a remainder of 29.
Put 2 as the next digit of the answer. 
Result so far: 9102.0
Subtracting 1734 from 1763 leaves us with 29.
Include the next digit (0) from the dividend after 29, then repeat: 290 / 867

Going ahead to step 8:
867 can be fit into 290 0 times, resulting in a remainder of 290.
Use 0 as the next digit of our solution. 
Result so far: 91020.0
If we subtract 0 from 290, we get 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

Step 9:
867 goes into 2900 3 times with a remainder of 299.
The number 3 becomes the next digit in our result. 
Result so far: 91020.3
Subtract 2601 from 2900 to get 299.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2990, and continue the process.

Advancing to step 10:
867 goes into 2990 3 times with a remainder of 389.
The next digit of our result is 3. 
Result so far: 91020.33
Subtract 2601 from 2990 to get 389.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3890, and continue the process.

The final outcome is 91020.33, with a leftover of 0.389.
